In order to identify theapplication techniques of wooden lacquerware artifacts, optical/polarized lightmicroscopy, Fourier transform infrared (FT-IR) spectroscopy, and scanningelectron microscopy (SEM) equipped with energy dispersive X-ray analysis (EDX)were conducted on the lacquer films of 61 wooden lacquerware artifactsexcavated from the Imdang-dong site, Gyeongsan, Korea. Powdered soil, soot, andcharcoal were used as a filler for the undercoat, and iron oxide (Fe2O3) wasused as a red pigment. Five different applying techniques were identified forthe undercoat according to the composition of the lacquer. Eight differentapplication techniques were identified for the final coat (on the middle layerand surface layer). Totally seventeen application techniques were identifiedbased on the combination methods of the undercoat and finalcoat. Consequently,the undercoating techniques of Imdang-dong lacquerwares were found to besimilar to those of lacquerwares from excavated in other provinces. However,the use of iron oxide as a red pigment at Gyeongsang province is verycharacteristic compared with others.
